Description

Technical Field

[0001] This utility model relates to the technical field of recording classroom equipment, and in particular to a mobile overhead pickup for recording classrooms. Background Technology

[0002] A microphone is a device used to collect ambient sound and transmit it to backend equipment. It consists of a microphone and an audio amplifier circuit.

[0003] For example, Chinese document CN211880568U describes a mobile suspended track microphone for a recording classroom. The microphone includes a track mounted on a wall top via a first mounting plate and first screws. The top surface of the track has a square groove that slidably connects to an I-beam connecting block. The I-beam connecting block is fixedly connected to a hanging wheel mounting frame, on which a hanging wheel is mounted. The hanging wheel is slidably connected to the track. One end of a first connecting rope is fixedly connected to the right side of the I-beam connecting block, and the other end of the first connecting rope is fixedly connected to a rope take-up reel. The rope take-up reel is fixedly sleeved on the power output shaft of a motor. A second connecting block is fixedly mounted on the bottom surface of the hanging wheel mounting frame, and the bottom surface of the second connecting block is fixedly connected to one end of a second connecting rope. The other end of the second connecting rope is connected to the microphone. When the microphone needs to be moved left or right, the motor is started, causing the rope take-up reel to rotate and tightening the first connecting rope. This causes the first connecting rope to pull the hanging wheel, thereby moving the microphone.
